Symantec recommends the following configuration when you perform snapshot backups:

• The volume(s) that contains the Exchange databases should be dedicated to Exchange only. Other types of databases (for example, SQL Server) should not reside on the volume(s). Only Exchange objects are included in a snapshot backup.

• Transaction logs or Exchange system files should not reside on the same volume as the Exchange database files (edb and stm).

• (Exchange 2003, pre-Service Pack 1) The Information Store must be configured with only one database per storage group.

• (Exchange 2003 SP1 or later, Exchange 2007) Restore all databases in a storage group at the same time. Also restore all the databases before the transaction logs are committed and the databases are mounted. Transaction logs are committed at a storage group level, rather than at a database level.

• For off-host backups using Storage Foundations for Windows (SFW), SFW deports and imports at the disk level. The volumes that you back up must constitute whole disks.
